I le taimi muamua Na matou vaʻavaʻai i le tele o mataupu o le faʻaogaina o tala faʻapitoa i pisinisi, e aofia ai faʻatautuʻi ma polokalama faʻamaoni.
O le asō o le a tatou talanoa ai pe faʻafefea ona faʻaleleia e tala faʻamatalaga ma aseta atamai le manino ma le faʻamaoni o mea tau tupe e pei o filifiliga, lumanaʻi ma pili.
Filifiliga
O se filifiliga o se konekarate faafesuiaiga lea e tuʻuina atu ai i le tagata faʻatau le aia tatau e faʻatau ai se aseta i se tau faʻapitoa poʻo leʻi oʻo i se aso patino, ae e le faʻatagaina o ia e faia.
O le faʻatinoga o le filifiliga e mafai ona faʻapea:
Matou te faʻaaogaina se aseta atamai mo filifiliga lava latou o se meafaigaluega ma se tala atamai mo le tagata auai o loʻo galue o se fefaʻatauaʻiga ma tuʻuina atu filifiliga. Ua folafola e le sui auai o le fesuiaiga o le a ia faatauina atu se aofaiga o se aseta faapitoa i se tau faatau atu i le va o le maeʻa o le amataga ma le maeʻa o le poloka maualuga).
I totonu o le tulafono o aseta atamai, o le a matou siakiina na o le fefaʻatauaʻiga i le va o maualuga faʻamaonia, ma o le a le siakiina se isi mea; matou te tuʻuina atu tiute uma mo le tausisia o tulafono i le tulafono a le sui auai.
Tulafono o aseta atamai:

O le a tatou manatu o gaioiga e faia e pei ona taʻua i lalo: e faʻatau atu e se sui auai faʻatau filifiliga e faʻatau ai se aseta, ma e mafai e isi tagata auai ona tuʻuina atu nei filifiliga pe fefaʻatauaʻi. Ina ia faʻaaogaina lana aia tatau e faʻatau ai, e tatau i le tagata faʻatau faʻatau ona tuʻuina atu le numera manaʻomia o filifiliga i le teugatupe a le tagata faʻatau, o lona uiga, o le sui sui.

I totonu o le tulafono faʻamatalaga atamai, e tatau ona tatou mautinoa o soʻo se ExchangeTransaction e ui atu i ai mo le gaioiga mulimuli o le faʻatau ma le faʻatau atu e fetaui ma tulaga faʻamaonia, ma e faʻatau e le tagata auai le numera o iunite na ia lafoina i le teugatupe a le sui auai. E tatau i le tagata faʻatau faʻatau ona tuʻuina atu le DataTransaction saʻo e uiga i le fesiitaiga ina ia mafai ai e le sui o le fesuiaiga ona aloese mai tupe faʻaalu faalua. I lenei DataTransaction, e tuʻuina e le tagata faʻatau, e tusa ai ma le ki e tutusa ma lona tuatusi, o se tau e tutusa ma le numera o filifiliga na tuʻuina atu i le teugatupe a le sui auai, o lona uiga, le numera o aseta e mafai ona ia faʻatau.

Lumanai i luga o tala atamai
E le pei o se filifiliga, o le lumanaʻi (konekarate i le lumanaʻi) e le o se aia tatau, ae o se noataga a le tagata faʻatau e faʻatau se aseta i se tau na faʻatulagaina e le konekarate i se taimi i le lumanaʻi.
I se tulaga lautele, o le tusiaina o se lumanaʻi e tutusa ma le tusiaina o se filifiliga. O iinei o le aseta atamai e galue o se lumanaʻi.
E tatau fo'i ona e fa'amautinoa e saini uma e le fa'atau ma le fa'atau le fa'atauga fa'atau. O le lumana'i o se matafaioi e tatau ona fa'ataunu'uina i so'o se tulaga. O lona uiga afai e teena e le tagata faʻatau poʻo le tagata auai a latou noataga, soʻo se tagata auai i le fesoʻotaʻiga e mafai ona auina atu se fefaʻatauaiga, ma faʻataunuʻu ai le lumanaʻi.
O le tusi aseta atamai e pulea uma TransferTransactions ma ExchangeTransactions o le aseta i le lumanaʻi, faʻamaonia i latou pe a fai na faia e le tagata faʻatau se faʻatonuga mo se faʻatauga o le lumanaʻi aseta mai le sui sui.
O lenei poloaiga e tatau ona faʻamaonia ma faʻamalieina tulaga o loʻo tuʻuina atu ai le lumanaʻi. Ina ia faʻamaonia se faʻatonuga, e mafai ona e ulufale i ona fanua uma i le setete o le faʻatau a le faʻatau faʻatasi ma le faʻataʻitaʻiga o le byte o le faʻatonuga sainia, ona faʻatino lea o faʻamaoniga i fafo.
I le taimi nei, o le RIDE e le o iai se galuega faʻapitoa mo le faʻavasegaina o fefaʻatauaiga, ae aofia ai meafaigaluega uma e manaʻomia mo lona faʻatinoga. O le mea lea, e mafai e le au atinaʻe ona taumafai e faʻatino lenei uiga ia i latou lava.
